A strong password is essential for protecting your online accounts. This tool generates cryptographically secure passwords using your browser's built-in random number generator. No data is sent to any server.
Yes. We use the Web Crypto API (crypto.getRandomValues) to generate cryptographically secure random numbers. This is the same method used by modern browsers for TLS encryption.
No. Everything happens in your browser. Passwords are not sent to any server, and recent passwords are only kept in your browser session (page memory) and disappear when you close the tab.
At least 12 characters for general accounts, 16+ for sensitive accounts like banking or email. Longer passwords are exponentially harder to crack.
Entropy measures password randomness in bits. Higher entropy = harder to guess. 50+ bits is decent, 80+ is strong, 128+ is excellent.
